Abstract

Se evaluaron metodologías para la obtención de altas concentraciones de bacterias magnetotácticas (MTBs), ensayando medios de cultivo sintético (líquido, sólido y semisólido) y natural (sedimento estéril enriquecido). Se realizó enriquecimiento de muestras obtenidas en las represas de La Fe y de El Peñol, Antioquia - Colombia, adicionando soluciones de vitaminas, minerales y FeCl3. Los resultados obtenidos mostraron que la adición de nutrientes a las muestras incrementa la concentración de MTBs después de 4 semanas de incubación. Considerando la dificultad para el cultivo de estos microorganismos, los resultados de este estudio constituyen un avance que perfeccionado permitirá la síntesis biogénica a gran escala de nanocristales magnéticos con uso potencial en nanotecnología y biomédicina.
